The invention provides a solid lubrication treatment method for a friction pair laser micro-texture surface. The method comprises the steps that a micro-pit shape is machined on the surface of a friction pair through the laser surface texturing technology; all components in a self-lubrication composite are evenly mixed and dried to be used later; the surface micro-pit in a pre-treated die is filled with the self-lubrication composite through a die hot-press curing filling method; pressure maintaining hot-press curing filling is conducted through a hot press; then, the filled friction pair is heated for 20 min at the temperature of 250 DEG C and then protected by 99.9% of N2 to be heated for 30 min at the temperature ranging from 370 DEG C to 385 DEG C, insulating sintering is conducted for 0.5 h-1.0 h, and sintering forming is conducted after cooling; and solid lubrication can be finished after surface posttreatment. According to the method, the high-temperature sliding friction performance of the self-lubrication surface of a micro-texture can be improved, a good lubricating effect can be achieved under the conditions such as the high temperature and the high pressure, the bearing capability of a nanometer composite solid lubricating agent is effectively improved, and the nanometer composite solid lubricating agent can be applied under some complex and strict work conditions.

The invention relates to an organic solar cell based on a spray-coated molybdenum trioxide anode buffer array. The solar cell adopts an inverted structure, including a substrate layer, an ITO transparent conductive cathode layer, a cathode buffer layer, and a photoactive layer arranged in sequence from bottom to top. , anode buffer layer, metal anode layer; the anode buffer layer is a molybdenum trioxide array film formed by spraying an ammonium molybdate aqueous solution mixed with hyaluronic acid on the photoactive layer and annealing; in the molybdenum trioxide array film, hyaluronic acid The mass fractions of ammonium molybdate and ammonium molybdate are: 0.2-1wt% ammonium molybdate; 0-0.5wt% hyaluronic acid. The invention also discloses the preparation method of the battery; the invention forms a hyaluronic acid layer on the photoactive layer by adding hyaluronic acid into the ammonium molybdate aqueous solution, the precursor of molybdenum trioxide, and the introduced hanging chemical bonds can make The molybdenum trioxide layer forms a good ohmic contact with the active layer, which improves the performance of the battery.
